Subject: [PATCH v1 03/13] x86: rename 'cbm_type' to 'psr_val_type' to make it general
Date: Wed, 9 Aug 2017 15:41:42 +0800 [thread overview]
Message-ID: <1502264512-4648-4-git-send-email-yi.y.sun@linux.intel.com> (raw)
In-Reply-To: <1502264512-4648-1-git-send-email-yi.y.sun@linux.intel.com>
This patch renames 'cbm_type' to 'psr_val_type' to make it be general.
Then, we can reuse this for all psr allocation features.
